CHAPTER 13: MEASURING THE PERFORMANCE OF THE ECONOMY
INTRODUCTION
How is the economy performing?
What are our economic prospects?
Are things going to improve and, if so, when?
This leads the economist to ask….
What criteria should be used?
How can these criteria be quantified or measured?

13.2 MEASURING THE LEVEL
OF ECONOMIC ACTIVITY:
GROSS DOMESTIC PRODUCT
• The first step in measuring economic growth is to determine a country’s
total production of goods and services in a specific period.
• Performed by the national accounting sections of Statistics South Africa
(Stats SA) and the South African Reserve Bank (SARB).
• The central concept in the national accounts is the gross domestic product
(GDP).

One of the major problems that national accountants
have to deal with is the problem of double counting.

miller at R10 per bag, yielding a total of R10 000.
R10 000
• The miller processes the wheat into flour, which he then

+ R18 000
• After baking bread with the flour, the baker sells it to a+ shop

for R18 000.
= R61 500
• The shop subsequently sells the bread to final consumers for
R21 000.

Expenditure method
The expenditure method estimates GDP by adding up all the components
of final demand. This is the sum of the spending by households, firms, the
government and the ROW on final goods and services produced in the
domestic (SA) economy.
Or
The expenditure approach measures GDP as the sum of consumption
expenditure, investment, government purchases of goods and
services, and net exports.

Relationship between GDE and GDP
• GDE = C + I + G
• GDP = C + I + G + X – Z
Thus: GDP = GDE + (X–Z)
If GDP > GDE, then X > Z (ie (X–Z) is positive)
If GDP < GDE, then Z > X (ie (X–Z) is negative)
Important point
The difference between domestic spending and domestic
production is reflected in the balance of payments.

MEASURING PRICES: THE CONSUMER PRICE INDEX
LO: Define and interpret the CPI
Constructing a price index
By using the prices and the contents of the CPI basket it is possible to
calculate the CPI. The formula is:
Cost of basket in current period
* 100
Cost of basket in base period
Furthermore, note that a major purpose of the CPI is to measure inflation.
The inflation rate is the percentage change in the price level from one
year to the next. The inflation formula is:
(CPI of this year - CPI of the previous year)
* 100
CPI of the previous year
